The simulated multiple PIT transmission spectra (a) and the calculated group delay (b) with different Fermi levels of graphene. The inset in (a) shows the unit cell of our proposed structure composed of symmetric double-strip and a ring with graphene integration. (c) the evolution of the transmission spectrum versus Fermi energy and frequency. (d) Modulation depth of Peak A/B/C against the Fermi energy of graphene.
